But it goes to work only when it gets the signal that electricity's needed, like when you use the starter motor to crank your engine. Or when you operate your radio while the engine's not running. Then those chemicals go to work on each other. They change into different chemicals to "discharge" electricity. This can keep going on until the chemical action fades out. Then the battery's "dead discharged. It can't supply any more electricity. But your battery's got more lives than a cat. When the engine starts, the battery charging system kicks in. This is the voltage regulator and the alternator or generator. Charging turns the chemicals back like they were. The chemicals can start all over again. And the battery can keep on producing electricity. This back-and-forth chemical action goes on until the battery is worn out. It can't be recharged any more.
